In this post I want to give a little information about the parts of a computer hard drive, As some parts as below:
Is the boot sector of a sector hard disk, floppy disk, or similar data storage device that contains code for booting programs (usually, but not necessarily, operating systems) stored in other parts of the disk. On IBM PC compatible machine BIOS select boot device, then copy the first sector of the device (which may be an MBR, VBR or executable code), to address location 0x7C00. Cluster Cluster, or allocation units (allocation unit) in some file systems (file system) and the organization of the disk, such as File Allocation Table in MS-DOS operating system and NTFS in Windows NT refers to a collection of storage media sectors used by the operating system as a whole , which can be used to store information in the file or directory. The cluster is intended to reduce the extravagance in the conduct of the management structure of the data on your hard disk, so the file system will not allocate physical disk sectors, but a set of mutually bedekatan sector. Cylinder A disk drive cylinder is a division of data in disk drives, as used in the CHS addressing mode hard disk (or floppy disk). It is also used in the Cylinder-Head-Record (CCHHRR) addressing mode CKD disks. The concept is concentric, hollow, cylindrical slices through the physical disk (disk), collect each circular parallel tracks through the stack of plates. Sector In the context of computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disk. Each sector stores a fixed amount of data. Typical format of this media to provide space for 512 bytes (for magnetic disk) or 2048 bytes (for optical discs) of data that can be accessed users per sector. FAT File system FAT or FAT File System is a file system that uses a file allocation table structure as the way he operates. For cutting, most people refer to the FAT file system as FAT only. The word itself is FAT stands for File Allocation Table, which, if freely translated into Indonesian the File Allocation Table. FAT Architecture is now being used widely in computer systems and memory cards used in digital cameras or portable media players. Platter A hard disk platter (or disk) is a component of a hard disk drive: This is a circular magnetic disks where data is stored. The nature of rigid plates on a hard drive is what gives them their name (as opposed to the flexible material used to make a floppy disk). Hard drives usually have several platters mounted on the same spindle. A platter can store information on both sides, which requires two heads per platter. Hard disk recorder A hard disk recorder is a type of recording system that uses high-capacity hard disk to record digital audio or digital video. Hard disk recording systems represent an alternative to more traditional reel-to-reel tape or cassette multitrack systems, and provide editing capabilities unavailable to tape recorders. The system, which can be independently or based computer, typically include provisions digital mixing and processing audio signals. Host adapter In computer hardware, a host controller, host adapter, or host bus adapter (HBA) connects the host system (computer) to the other network and storage devices. This term is mainly used to refer to a device for connecting SCSI, Fibre Channel and eSATA devices, but devices for connecting to IDE, Ethernet, FireWire, USB and other systems may also be called host adapters. Recently, the advent of iSCSI has brought about Ethernet HBAs, which are different from Ethernet NICs in that they include hardware iSCSI-dedicated TCP offload engine. Interleave When referring to a computer hard disk drives, interleaving is a method to make reading the data more efficiently. Interleaving is a method of organizing the sector on the hard disk drive of your computer, so the data will be arranged so that the read / write head can access information more easily, so the data is read from the hard disk faster. Logic Board A logic board is Apple Macintosh equivalent to the motherboard. The term logic board was created back in the 1980's, when the compact Macs at the moment has two separate circuit components. The term logic board stuck over the years from manufacturing Macintosh, even in non-all-in-one Mac. A long time for Apple's current practice of existing models are upgraded to offer an upgrade logic board where users can bring their computer to the Apple dealer and have the old motherboard was replaced with a new one, along with other upgrades needed to bring their computer in line with specifications new model. The old motherboard will be stored by the dealer as a trade in. SCSI Small Computer Systems Interface, or SCSI (pronounced scuzzy [1]), is a set of standards for physically connecting and transferring data between computers and peripheral devices. SCSI standards define commands, protocols, and electrical and optical interfaces. SCSI is most often used for hard disks and tape drives, but can connect a variety of other devices, including scanners and CD drives. SCSI standard defines command sets for specific types of peripheral devices; the presence of "unknown" as one of this type means that in theory, can be used as an interface for virtually any device, but the standard is very pragmatic and addressed toward commercial requirements. Motor Spindles Spindle motor, also sometimes called a spindle shaft, is responsible for changing the hard disk platter, allowing hard drives to operate. Spindle motor is a kind of "work horse" of the hard disk. It's not flashy, but should provide stable, reliable and consistent power to change thousands of hours of continuous use frequently, to enable the hard disk to function properly. In fact, many actual drive failures with the spindle motor failure, not a data storage system. Thus the parts of a computer hard drive may be useful!
